Product Description
Product overview
Perrigo Tretinoin Cream, USP 0.05% is a prescription-strength retinoid cream containing all-trans retinoic acid — the gold-standard, FDA-approved active for treating acne vulgaris, reducing fine lines, fading hyperpigmentation, and improving overall skin texture. This medium-potency formula accelerates cell turnover at the deepest level without requiring any conversion steps in the skin.
Gold-Standard Retinoid
Tretinoin is the only FDA-approved topical ingredient proven to treat acne, reduce wrinkles, and stimulate collagen production. No conversion needed — it works immediately at the cellular level.
Texture & feel
SENSORYGold-Standard Retinoid
Tretinoin is the only FDA-approved topical ingredient proven to treat acne, reduce wrinkles, and stimulate collagen production. No conversion needed — it works immediately at the cellular level.
Medium-Strength 0.05%
Ideal step-up concentration for users who have tolerated 0.025%. Delivers faster results for acne, fine lines, and hyperpigmentation than lower strengths.
Cream Base for Comfort
Emollient cream vehicle with stearic acid and stearyl alcohol provides more moisturizing delivery than gel formulations, making it better suited for normal-to-dry skin types.
Clean Minimal Formula
Only 9 total ingredients with zero fragrances, parabens, silicones, or sulfates. A streamlined pharmaceutical formula that minimizes irritation risk from unnecessary additives.
Safety & compatibility
SAFETretinoin is classified as FDA Pregnancy Category X (teratogenic). Do not use during pregnancy, when planning to conceive, or while breastfeeding. Consult your physician for safe alternatives.
Contains Isopropyl Myristate, a fatty acid ester that can serve as a lipid source for Malassezia yeast. If you have fungal acne, consider a tretinoin gel formulation instead.
Tretinoin significantly increases UV sensitivity, especially in the first weeks. Daily broad-spectrum SPF 30+ is mandatory. Avoid prolonged sun exposure and tanning beds.
Initial increased breakouts, peeling, redness, and dryness are normal as tretinoin accelerates cell turnover and pushes trapped debris to the surface. This typically subsides with continued use.
Do not use on the same night as AHAs (glycolic/lactic acid), BHAs (salicylic acid), benzoyl peroxide, or vitamin C serums at low pH. These combinations significantly increase irritation risk.
Works well with hyaluronic acid, niacinamide, ceramides, and gentle moisturizers. The "sandwich method" (moisturizer → tretinoin → moisturizer) helps reduce irritation.
Ingredient breakdown
INGREDIENTSTretinoin (All-Trans Retinoic Acid) 0.05%Proven
The gold-standard prescription retinoid and the only FDA-approved topical ingredient for anti-aging. Unlike OTC retinol, tretinoin requires zero conversion steps — it is already in its bioactive retinoic acid form and works immediately on skin cell receptors to accelerate turnover and boost collagen.
- FDA-approved: For treatment of acne vulgaris; extensively studied for photoaging
- Mechanism: Decreases follicular epithelial cell cohesiveness, reduces microcomedone formation, and stimulates mitotic activity
- Bioavailability: Less than 0.3% of topically applied dose is systemically absorbed
- Clinical data: 69–74% average reduction in acne lesion counts after 12 weeks of use
Isopropyl Myristate ~4–6%Functional
A clear, colorless emollient that improves product spreadability and enhances penetration of active ingredients into the skin. Gives the cream a smooth, non-greasy slip and helps tretinoin absorb more effectively.
- Function: Emollient, penetration enhancer, and texture agent
- Absorption: Fast-spreading, reduces greasy feel of oil-rich formulations
Stearic AcidFunctional
A naturally occurring fatty acid that acts as an emollient, thickener, and emulsion stabilizer. Helps create the cream's smooth, rich texture while reinforcing the skin's protective barrier.
- Function: Emollient, emulsifier, and texture enhancer
- Benefit: Softens skin and prevents moisture loss
BHT (Butylated Hydroxytoluene)Preservative
A synthetic antioxidant that protects the formula from oxidative degradation. Helps maintain tretinoin potency over time by preventing breakdown from light and air exposure.
- Function: Antioxidant stabilizer and preservative
- Safety: FDA-approved for cosmetic use; concerns come primarily from oral ingestion studies, not topical application
9 ingredients
Tretinoin 0.05%, Stearic Acid, Isopropyl Myristate, Polyoxyl 40 Stearate (PEG-40 Stearate), Stearyl Alcohol, Xanthan Gum, Sorbic Acid, Butylated Hydroxytoluene (BHT), Purified Water
Where it fits in your routine
ROUTINEApply at night only. Use the "sandwich method" (moisturizer → tretinoin → moisturizer) if experiencing dryness. Always follow with SPF 30+ the next morning.
How to use
HOW TO USECleanse Gently
Wash face with a gentle, non-foaming cleanser. Pat dry completely. Wait 20–30 minutes until skin is fully dry — applying to damp skin increases irritation.
Apply a Pea-Sized Amount
Squeeze a pea-sized amount onto your fingertip. Dot evenly across forehead, cheeks, chin, and nose. Gently spread in a thin, even layer across the entire face.
Avoid Sensitive Areas
Keep away from eyes, mouth, corners of the nose, and mucous membranes. Do not apply to sunburned, windburned, broken, or eczematous skin.
Moisturize & Protect
Wait 10 minutes, then apply a gentle moisturizer with ceramides or hyaluronic acid. The next morning, apply broad-spectrum SPF 30+ sunscreen — this step is non-negotiable.
Build Tolerance Gradually
Start with 2 nights per week for the first 2 weeks. Increase to every other night for 2–4 weeks. Then use nightly if your skin tolerates it well. If irritation is severe, reduce frequency.
Who is it for?
WHOPerfect for you if:
- You have moderate-to-severe acne vulgaris (inflammatory and comedonal)
- You want the most effective proven anti-aging treatment available topically
- You have hyperpigmentation, dark spots, or uneven skin tone
- You have already tolerated tretinoin 0.025% and want to step up
- You want to minimize pore size and improve overall skin texture
- You are committed to a consistent nighttime routine and daily sunscreen use
Consider alternatives if:
- You are pregnant, planning to conceive, or breastfeeding (Category X)
- You have fungal acne (Malassezia folliculitis) — choose a gel formulation instead
- You have active eczema, rosacea, or severely compromised skin barrier
- You have never used any retinoid before (start with 0.025% or OTC retinol first)
- You cannot commit to daily sunscreen use
- You have extremely sensitive or reactive skin prone to severe irritation
Skin type compatibility
SKIN TYPESTretinoin regulates sebum production and reduces shine over time. The cream base absorbs well without adding excessive oiliness. Outstanding for oily, acne-prone skin.
Cream vehicle is more moisturizing than gel alternatives. However, expect increased dryness and peeling initially. Layer with rich ceramide moisturizer and use the sandwich method.
Works beautifully for combination skin types. Normalizes oil production in the T-zone while the cream base helps keep drier areas comfortable.
0.05% may be too strong for very sensitive or reactive skin. Start with 0.025% concentration or buffer with moisturizer. Consult your dermatologist before use.
This is what tretinoin was made for. FDA-approved for acne treatment with decades of clinical evidence. Expect purging in weeks 2–6 before significant clearing. Note: not fungal-acne safe due to Isopropyl Myristate.

DUPES
Another generic tretinoin cream with nearly identical formulation and the same 0.05% concentration. Bioequivalent to Perrigo. Price varies by pharmacy — ask your pharmacist which generic is cheapest.
OTC third-generation retinoid with comparable acne-fighting efficacy and significantly less irritation. Less potent for anti-aging and wrinkles, but no prescription needed and much more affordable.
OTC retinol (not tretinoin) that requires conversion in the skin — significantly weaker but much gentler. Good starting point for retinoid beginners who want anti-aging benefits without prescription.

Yes — both 20g and 45g tubes are under 100ml/3.4oz TSA limit. Compact aluminum tube fits easily in toiletry bags.
Frequently asked questions
FAQNo. Tretinoin is classified as FDA Pregnancy Category X, meaning it is teratogenic and poses significant risks to a developing fetus. It is absolutely contraindicated during pregnancy, when trying to conceive, and while breastfeeding. Women of childbearing age should use effective contraception while on tretinoin. If you become pregnant, discontinue use immediately and consult your doctor. Safe alternatives during pregnancy include azelaic acid or certain gentle peels recommended by your dermatologist.
No. This cream formulation contains Isopropyl Myristate, a fatty acid ester that can serve as a lipid source for Malassezia yeast, potentially triggering or worsening fungal acne (pityrosporum folliculitis). It also contains Stearic Acid and PEG-40 Stearate, which may also feed the yeast. If you have fungal acne, ask your dermatologist for a tretinoin gel formulation instead, which typically uses a simpler water-alcohol base without these fatty esters.
Avoid using tretinoin on the same night as AHAs (glycolic acid, lactic acid), BHAs (salicylic acid), benzoyl peroxide, or low-pH vitamin C serums (L-ascorbic acid). These combinations can cause severe irritation, redness, and barrier damage. You can alternate nights — for example, tretinoin on Monday/Wednesday/Friday and vitamin C or exfoliating acids on alternate evenings. Ingredients safe to combine with tretinoin on the same night include hyaluronic acid, niacinamide, ceramides, and gentle peptide serums.
Tretinoin Cream 0.05% is most suitable for oily, combination, and acne-prone skin types. The cream base also makes it comfortable for normal-to-dry skin compared to gel formulations. It is moderately suited for dry skin when paired with rich moisturizers. It may be too strong for very sensitive or reactive skin — those individuals should start with 0.025% or consider adapalene. Consult your dermatologist to determine the right strength for your skin.
Expect an initial adjustment period of 2–4 weeks with dryness and possible purging. Most users begin seeing noticeable improvements in acne around weeks 6–12. Anti-aging benefits (fine lines, firmness, tone) typically become visible at 3–6 months of consistent use. Maximum results for wrinkle reduction and collagen remodeling are seen at 6–12+ months. Patience is key — tretinoin is a long-term treatment, not an overnight fix.
Apply tretinoin at night only, after cleansing. Wait 20–30 minutes until skin is completely dry (applying to damp skin increases irritation). Apply a pea-sized amount as a thin layer to the entire face. Wait 10 minutes, then follow with moisturizer. In the morning, use a gentle cleanser, hydrating serum, moisturizer, and SPF 30+ sunscreen. Never apply tretinoin during the day or before sun exposure.
The cream formulation has a moderate comedogenic rating of approximately 3/5, primarily due to the Isopropyl Myristate in the base. However, tretinoin itself is powerfully anti-comedogenic — it unclogs pores and prevents new comedones from forming. In practice, the acne-clearing benefits of tretinoin far outweigh the comedogenic potential of the cream base for most users. If you are highly prone to clogged pores, consider asking for a gel formulation, which uses a lighter base without fatty esters.
Use within 6 months of opening for optimal potency. Tretinoin is sensitive to light and air exposure, which causes degradation over time. A 20g tube typically lasts 2–4 months with nightly facial use (a pea-sized amount covers the full face). A 45g tube can last 4–6+ months. Always keep the tube tightly closed and store at room temperature, away from direct sunlight. Discard if the cream changes color or consistency.
Verdict: Perrigo Tretinoin Cream, USP 0.05% is the real deal — a clinically proven, FDA-approved prescription retinoid that delivers unmatched results for acne, wrinkles, hyperpigmentation, and overall skin texture improvement. With only 9 clean ingredients and no fragrances, parabens, or silicones, it is a streamlined pharmaceutical formula that lets the active ingredient do the heavy lifting. The cream base is comfortable for most skin types, and as a generic alternative to Retin-A, it offers excellent value. The trade-offs are real: an unavoidable adjustment period with dryness and purging, mandatory sunscreen use, pregnancy contraindication, and the cream base is not ideal for fungal acne. But for those willing to commit to the process and work with their dermatologist, tretinoin 0.05% is the single most effective topical skincare treatment available — backed by decades of clinical evidence and millions of satisfied users worldwide.

Understanding Simple Alcohols
Alcohol ingredients are widely used in cosmetics and come in different types. For the most part alcohols are not problematic at all. However one type of alcohols, simple alcohols can be quite drying to the skin because it evaporates very quickly. This can cause irritation which can also lead to other skin complications. These alcohols should never be used alone on your skin, but combined with other cosmetic ingredients, they are normally without issue. However, for some people with sensitive and easily irritable skin, avoiding products with these simple alcohols may be beneficial.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.

EU Allergen-Free
Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.

Fungal Acne (Molassezia) Safe
Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
What are Notable Effects & Ingredients?
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Pro Tip Alert!
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

What is the Ingredient Safety Breakdown?
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
Pro Tip Alert!
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
